Abstract
Disclosed is a rubber molded body formed from a rubber composition. The rubber composition contains a natural rubber and a butadiene rubber as predominant rubber components; a low-melting paraffin wax having a melting point of 45° C. to 57° C.; and optionally a low-melting fatty acid amide having a melting point of 35° C. to 85° C. The mass ratio of the natural rubber to the butadiene rubber ranges from 80/20 to 10/90. The amount of the low-melting paraffin wax contained in the rubber composition ranges from 20 to 70 parts by mass per 100 parts by mass of all rubber components. The total amount of the low-melting paraffin wax and the low-melting fatty acid amide contained in the rubber composition ranges from 30 to 100 parts by mass per 100 parts by mass of all rubber components.
